    Abstract: A level shifter for outputting an output voltage having a voltage level range different from a voltage level range of a received input voltage is disclosed. The level shifter includes: a current mirror configured to copy a reference current flowing through a first mirror transistor to a second mirror transistor; a current mirror control circuit electrically connected to the current mirror by a sink node and including a plurality of control transistors configured to control the current mirror; and an output circuit configured to output an output voltage based on a voltage level of the sink node, wherein a first control transistor of the plurality of control transistors receives the output voltage fed back to a gate terminal of the first control transistor, and a second control transistor of the plurality of control transistors receives an inverted output voltage fed back to a gate terminal of the second control transistor.
